Rear

DESCRIPTION
The rear wheel bearings are of a cartridge design and are pregreased, sealed and require no scheduled maintenance. The rear wheel bearings are preset and cannot be adjusted. If a bearing is disassembled for any reason it must be replaced as a unit. No individual service seals, rollers or races are available. The hub nut torque of 255-345 Nm (188-254 ft. lbs.) restricts rear wheel bearing/wheel hub relative movement and maintains axial position of the rear hub. Due to the importance of the wheel hub nut torque/tension relationship, take the following precautions during service.

PROCEDURE
1. Since the rear wheel bearing cannot be adjusted, the rear axle wheel hub retainer must not be backed off after reaching the required torque of 255-345 Nm (188-254 ft. lbs.) during installation.
2. The rear axle wheel hub retainer and washer assembly must be replaced with a new rear axle wheel hub retainer and washer assembly whenever the rear axle wheel hub retainer is backed off or removed. Never reuse the rear axle wheel hub retainer.
3. Power tools must not be used to tighten the rear axle wheel hub retainer or rear wheel bearing damage will result. Use a torque wrench.
4. The rear hub and rear wheel drive shaft and joint splines have an interference fit requiring special tools for disassembly. The rear axle wheel hub retainer can be used to accomplish assembly.

RUNOUT
Runout of the wheel flange is an infrequent, but possible cause of rear end vibration. It is advisable to check the runout of the:





- Pilot (radial), maximum runout 0.15 mm (0.006 inch).





- Flange face (lateral), maximum runout 0.25 mm (0.010 inch).





- Bolt circle (radial), maximum runout 0.38 mm (0.015 inch).
